たものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a grinding wheel used in a high-speed grinding device, particularly a super-hard grinding composite grinding wheel, which is capable of extremely finely graining high-hardness materials. This made it possible to do it rationally and economically.

使用することは経−的に不可能である。Recently, there has been a growing need for ultra-fine pulverization of particularly hard materials, but conventional hydrifite-based and other grinding wheels are not suitable for ultra-fine pulverization of materials with hardness equivalent to or higher than abrasive grains. The wear and tear on the equipment was so great that it was not possible to maintain stable production over a long period of time. To solve this,
Ultra-hard abrasive grains such as diamond or borazone (a trade name for boron nitride abrasives) can be used, but these abrasive grains are extremely expensive and should not be used over the entire grinding surface of the wheel. - It is impossible.

を特徴とするものである。In other words, the ultra-hard grinding composite grinding wheel of the present invention is coated with ultra-hard abrasive grains in a layer only on the part of the grinding wheel that is subjected to the most load during grinding. The grinding surfaces of the opposing outer circumferential convex portions are coated with ultra-hard abrasive grains, and the inner grinding surface is provided with a grindstone having a hardness lower than that of the grinding surfaces of the outer circumferential convex portions. .

の厚さを変えることもできる。In the present invention, diamond or borazone are used as the ultra-hard abrasive grains to be coated on the grinding surfaces of the opposing outer peripheral convex portions of the metal wheel.There are various methods for coating, but there are no particular limitations. No, but
For example, ultra-hard abrasive grains of about 50 to 100 mesh are metal bond coated on a metal surface using a nickel-copper bond. The appropriate ratio of bond used is 10 to 50 parts per 100 parts of abrasive grains. The width of the coating is 5-3
Although the width is preferably 0 m, since the coating is applied to the entire surface of the outer circumferential convex portion of the metal wheel, it is necessary to prepare the outer circumferential convex portion in advance to the above-mentioned width depending on the object to be ground. The thickness of the coating is preferably varied in the range of 0.1 to 5 - depending on the object, and the thickness of the layer can also be varied between the stationary side and the rotating side.

付設することができる。Examples of the grindstone having a hardness lower than the tIiIi degree of the outer grinding surface disposed on the inner grinding surface include a fine ceramic grindstone, a vitrified grindstone, a composite of a hydrified grindstone and a polymer, a metal grindstone, and the like. The grinding ridges on the internal grinding surface formed on these grindstones can be arranged, for example, according to the method described in Japanese Utility Model Publication No. 53-49091.

ものがある。As a result of various studies, it was discovered that the greatest load is applied to the convex portions of the outer periphery of the metal wheel that face each other during grinding, and the present invention was created by coating only these portions with ultra-hard abrasive grains. However, this provides the following advantages. That is, when grinding a high-hardness material using the combination grindstone of the present invention, gouges occur in the gently sloped part of the internal grinding surface adjacent to the ultra-hard abrasive coating layer, and the ultra-hard abrasive coating layer Even though it is still working, the grinding function of the grindstone stops and it becomes unusable. In this case, by replacing the grinding wheel with the internal grinding surface, which is much cheaper than the abrasive grains in the ultra-hard coating layer, it is possible to restore the function to the same level as new again, so even if the ultra-hard coating layer wears out, It becomes possible to repeat the exchange many times, and its economic effects are immeasurable.

可能であり、その利用効果はきわめて大である。In addition, when grinding inorganic materials, a porous grindstone such as a hydrified grindstone is used as a replacement grindstone for the internal grinding surface, and when grinding foodstuffs, a hydrified grindstone is used to prevent bacterial contamination and rot. A grindstone made of a composite of a grindstone and a polymer can be used, and different grindstones can be used and replaced depending on the object to be ground. Naturally, it is also possible to replace the internal grinding surface with fine ceramics or metal depending on the purpose, and the effects of this use are extremely large.
